The PSI5-interface acceleration sensor chip supports dual channels (X-axis/Y-axis) with the following key features:
1. Dual-channel accelerometer (MEMS X-axis/Y-axis with independent channels)
2. Compatibility with v1.3/v2.1, transmission rates of 125kbps/189kbps
3. MEMS sensor detection range (30/60 g/120/240/480 g)
4. PSI5 synchronous and asynchronous modes
5. PSI5 bidirectional communication
6. Operating temperature range of -40~125℃
7. ISO 26262
CMA2100B is a dual-channel (X-axis/Y-axis) accelerometer sensor with a PSI5 interface. It can be used in applications such as automotive airbag systems and acceleration data acquisition for chassis air suspension.
